A worker at the high-end Swiss jeweler Chopard became the city’s latest slashing victim when he bumped into a man who was blocking the door of a crowded subway train in Manhattan on Friday, police sources said.

Arman Telfeyan, of Mahwah, NJ, was boarding a northbound train at the N/Q/R station in Times Square around 8:15 a.m. when he made contact with his attacker, the sources said.

The slasher, described as an Indian man around 45 years old, stared at Telfeyan, then cursed at him, saying, “F–k you,” according to law-enforcement sources.

They got into an argument as the train continued moving uptown — and at 57th Street and Seventh Avenue, the attacker suddenly pulled a knife out of his pocket and sliced Telfeyan on his left cheek.

The victim was also slashed on the left thumb as he tried to defend himself.

The thug dashed off the train as it pulled into the next station.

Telfeyan got off the train at Fifth Avenue-59th Street, then walked to his job at Chopard’s corporate headquarters on East 63rd Street.

At work, one of his co-workers called police, and an ambulance arrived to take him to Lenox Hill Hospital, according to police sources.

Tel­fe­yan needed stitches to close the 1¹/₂-inch gash on his face, police sources said.

In the early afternoon, he showed up back to work with bandages on his face and thumb, then left a little while later in a black car without commenting.

A hardhat working across the street said he won’t be taking the subway anytime soon.

“I definitely won’t take it,” said James LaSalla, 31, of Staten Island. “I’m not trying to get slashed, but I can protect myself.

“I don’t want to witness anyone getting hurt. [It’s] not right. These people should get jobs,” he added.

Last week, NYPD Transit Bureau Chief Joseph Fox said felony crimes have shot up this year, with 36 percent more incidents in January than the same month in 2015.
